Cover Page for epub eBook and question about xhtml doctypes for Index and Glossary
Greetings,
I am evaluating different ebook editors and I am leaning toward RoboHelp 2020, however I have ran into a few issues. The most important being the cover page for the epub book I would be creating.
I have put a cover page in the Front Matter that is a Topic with only the Cover Page image, see image. In the Output eBook settings (set for epub) I have set the Cover Image to the same image. When I compile for eBook there is no xhtml page and the epub does not have a cover page. If I take out the cover in settings or take out Front Matter this still happens.

I looked in Sigil and the cover image is in the Images folder. I looked in the opf file and the information for cover is incorrect and is pointing only at the image. The file has:
in metadata
<meta content="image_cover" name="cover" />
and in manifest the id is wrong
<item id="cover-image" href="images/cover.png" media-type="image/png" properties="cover-image"/>
there is no reference in the spine or guide (this would be the references to the cover xhtml page)
Lastly, when I do open an epub file in Sigil it says there are errors. I have found the _index, when included, and _glossary xhtml files are missing the tag <!DOCTYPE html> before the html tag. Once in place Sigil no longer says the epub book has errors. Is this by design or a bug? I have tried to exclude the glossary but it still appears in the output, I can exclude the index. When I upload the file to Google Play Books the book fails processing, which is what I would expect since the cover is messed up.
Thoughts?
If you are explaining how to do something please go step by step since I am very new to RoboHelp 2020.
Cheers,
Noral
